Specification of Letters Patent.

Patented March 16, 1909.

Application filed May}, 1906, Serial No. 314,829. Renewed March 14,1907, Serial No. 362,416. Renewed June 16, 1908. Serial No. 438,880 i Toall whom it may concern:

Be it known that 1, Asnnn LAMnEnT, a citizen of the United States, andaresident of Newark, in the county of Essex and State of at any desiredheight or point in it's; transit.

The improved skip or load carrier refer ably consists of two arts orsections, inged or otherwise adjusta l united, so that it can be openedand close it is provided with points of connection with the hoist ropeso arranged that the su porting effort of the hoist rope automatica lycloses the two sections together and holds them closed during thetiine'the skip is suspended from the hoist rope. In addition to. this,other points of connection are provided on each section and a secondrope, called a tripping rope, is employed, so arrangedthat the supportof the skip can be transferred from one rope to the other and whentransferred to this second or tripping rope the two sections of the skipare separated and the skip is-opened to discharge its load. The hoistingrope is operated thus made taut the skip opens whenever and by a powerdriven drum in the usual manner;

the tripping rope is provided with a device for taking up the slack,called a take-up device; this consists of a suitable support or standardwith a weight and pulley; this rope. is also'provided with a device forchecking its movement so that it can be made tohalt -and take the weightof the loaded skip; when the hoisting rope is slacked and the trippingrope wherever the change of support from one rope to the other is made.

' I have shown my iinprovedskip in connection with a derrick but thearrangement of,

the hoisting and conveying apparatus may be widely varied.

The accompanying drawings illustrate the invention.

liigurel. shows the improved skip coniiected to the haul rope and thetripping rope; Fig. 2 is a view at right angles to Fig.

1; Fig. 3 shows the skip in its open position,

the support having been transferred fronr "support, and there is a chain25 with hooked terminals 26, 27 to detachably engage with the links 28,29 pivoted at 23, 24, as described. Therc is an iron I-bar t with aperforated ear 6, and this bar has loops 30 through which the chains 25are passed. There is a hook 31 fixed to the pulley block p and the hoistrope it passes around the pulley 32 in the pulley block 2). The positionof the exterior points of support 23 and 24 on the skip a are so fixedwith respect to the hinge 22 and the meeting lineof the two sections 20and 21 that the supporting effort of the hoist rope h acting through thechain 25 operates to draw the two sections 20 and 21 together. twosections may be locked together and 34 is a pin fixed to the end of asection of chain by which the clamp 33 is locked in position this isonly used when the skip is detached from any hoisting apparatus and islocated on a support beneath it, the clamp is not a necessary elementbut is useful when the filled skip istransported on a platform car, forinstance. On the outside of the skip at or near the center and near thelower edge are hooks 40, 41, one on each section. tis a trip ing ropeconnected with the ring 44; 43 is a iiook also connected with the ring44, and there is a chain or flexible connection 42, the opposite ends ofwhich engage the hooks 40 and 4] and serve to connect the hook 43therewith. 45 is a flexible connection between the ropes t and 71 itextends from the ring 44 on the tripping rope t to a perforated car 46on the pulley block 1). Pulley block p is of suiiicient weight tooverbalance counterweight 64, thus enabling the o erator to lower thepulley blockwhen no s ip or load is connected therewith.

Referring to Fig. 4, 10 is a vertical mast on the rotating platform 12pivoted at 14. The

33 is a clamp by means of which the boom 11 is pivoted at 13. 15 is-abrace fixed at one end to the earth and at its opposite end to the topof the mast. There is a m e 16 passing over the pulleys 50, 51, ,52, ana pulley at the bottom of the mast to the power driven drum 53. There isa rope 17 passing over the guide pulley 18 and engaglng thegroove in therotating platform 12. This is controlled by a power driven drum 54. Thehoist rope it passes from the power driven drum 55 over a pulley at thebottom of the mast 10, a pulley part way up the mast, and a pulley nearthe outer end of the boom, then around the pulley 32 in the block p andis fast to the link 56 at the end of the boom. The tripping rope textends from the ring 44 over a pulley in the outerend of the boom 11-,over a pulley near the bottom of the mast 10, under a pulley below themast 10, passes four times around the drum 60, thence under the pulley61 at the bottom of the fixed standard 63, over pulley 62 at the top ofthe standard 63 to the weight 64. This weight takes up the slack in therope t between the rin 44 and the weight 64. The drum 60 is contio ledby an angular lever 80 constituting a foot brake this is pivoted to asuitable support at- 84 and is connected by a link 81 with an arm 82fixed on a transverse shaft 88 journaled in the bedplate 90. The drum 60is rotatably .mounte on the bedplate 90 and consists of i the frictiondisk 83 and the pulley 79 fixed thereto. Rope t is passed around thepulley 79 three or four times to give it the necessary friction and thefriction disk 83 is shrrounded I by a steel band 85 fixed at one endtothe shaft 88, and at the other end to, an adjust- I able bolt 86. Thesteel band 85 is provided with wooden shoes 87 which on age theperiphery of the friction disk 83; w en the arm 82 is turned by thedepression of the lever 80,

. friction is ap lied to the disk 83 and the I lows:

grooved whee 79 is stopped in its rotation; this checks the movement ofthe tripping rope t. The link '81 may be of any linear extent and may besubstituted by a rope.

The 0 eration of the apparatus is as fol- Vl hen the skip a is loadedthe drum 55 is started, the hoist rope it exerts a supporting effort onthe skip a through the pulley block p and chain 25 ;.this su portineflort draws the two sections 20 an 21 of t e skip it together. When theski has been carried to a sufiicient height the com is placed in thenecessary position to locate the skip a over the point of discharge.Here the ski a is lowered more or less and while being lowered lever isdepressed andthe brake band is applied to the drum 60 at or about theheight where the discharge of the skip is desired, while the hoist ro eh is still lowering but immediately after 0 ecking the movement of thetripipng rope t, the section 45 conneein the two ropes t and it becomestaut and t e supporting effort is placed upon F'Tthe rope-t y'vhile therope it becomes slack; this results in changing the points of supportfrom 23-and '24 to 40 and 41, separates the sections 20 and 21 of theskip, and the load is dropped. By slacking aw ay on the rope t andhauling on the ropeh, the skip is again closed and this change from onesupporti n nope to the other may be made whenever an wherever it isdesired to open or close the skip. The power driven drum 55 is a meansfor varying the ion th of the hoisting rope and the drum 60 with thetake-up device and foot brake is a means. for varying the length of thetripping rope. v i
